Distribution and Frequency of Salivary Gland Tumours: An International Multicenter Study.

Background: Salivary gland tumours (SGT) are a relatively rare group of neoplasms with a wide range of histopathological appearance and clinical features. To date, most of the epidemiological studies on salivary gland tumours are limited for a variety of reason including being out of date, extrapolated from either a single centre or country studies, or investigating either major or minor glands only.

Methods: This study aimed to mitigate these shortcomings by analysing epidemiological data including demographic, anatomical location and histological diagnoses of SGT from multiple centres across the world.

Descriptive Epidemiology of Odontogenic Tumors in Nigeria: An African Oral Pathology Research Consortium Multicenter Study.

Background: Many studies have investigated the burden of odontogenic tumor (OT) in Nigeria; however, the true burden and prevalence of these lesions are not known because these studies are based on a center/region.

Aims: Hence, the aim of this study is to evaluate the true burden of OTs in Nigeria, using a multicenter approach.

Materials And Methods: This is a 10-year retrospective cross-sectional study of OT seen in eight tertiary health institutions in different geographic locations in Nigeria.

A geographical analysis of ethnic distribution of jaw ameloblastoma in Nigerians.

Descriptive epidemiology of salivary gland neoplasms in Nigeria: An AOPRC multicenter tertiary hospital study.

Objectives: Accurate diagnosis of salivary gland neoplasms (SGN) in many centers in Africa is limited by poor diagnostic resources and ancillary services. Hence, we have carried out a multicenter epidemiological study to understand the true burden of SGN in Nigeria.

Method: In this descriptive cross-sectional study, we have deployed resources available to members of the African Oral Pathology Consortium (AOPRC) to examine the burden of salivary gland lesions in Nigeria, using a multicenter approach.

A multi-centre evaluation of oral cancer in Southern and Western Nigeria: an African oral pathology research consortium initiative.

Introduction: Oral cancer is a leading cause of cancer deaths among African populations. Lack of standard cancer registries and under-reporting has inaccurately depicted its magnitude in Nigeria. Development of multi-centre collaborative oral pathology networks such as the African Oral Pathology Research Consortium (AOPRC) facilitates skill and expertise exchange and fosters a robust and systematic investigation of oral diseases across Africa.

A retrospective review of 61 cases of adenomatoid odontogenic tumour seen in five tertiary health facilities in Nigeria.

Introduction: Adenomatoid odontogenic tumor (AOT) is a benign lesion originating from the dental lamina or its remnants. It is a relatively uncommon neoplasm representing about 3% of all odontogenic tumors. The aim of this study was to examine the clinical and radiological characteristics of AOTs in five major tertiary centres in Nigeria.

Odontogenic tumors in Port Harcourt: South-South geopolitical zone of Nigeria.

Aim: A retrospective study of odontogenic tumors (OTs) in Port Harcourt was undertaken to establish its prevalence and compare with known data in the literature from Nigeria and elsewhere.

Materials And Methods: All pathologically diagnosed OTs between 2008 and 2013 at the archives of the Department of Oral Pathology and Oral Biology of the University of Port Harcourt/University of Port Harcourt Teaching Hospital were retrospectively studied and classified according to the 2005 WHO classification of OTs and allied diseases. These were recorded into a computer and analyzed using Statistical Package for Social Sciences (SPSS 21.

Knowledge of medical house officers about dental specialties.

Background: Some patients with oral diseases present initially to a general medical practitioner who is expected to refer the patients to the appropriate dental specialist for management. Thus they are expected to have a good knowledge of the different specialties in dentistry. This study was designed to determine the knowledge of medical house officers about the specialties in dentistry and how this will influence their ability to make appropriate referral.

Epidermoid cyst of the tongue causing airway obstruction.

Epidermoid cyst occurring within the tongue is rare. The aim of this article is to discuss the management of an adult patient who presented with respiratory obstruction due to this congenital epidermoid cyst within the tongue. A 32-year-old male patient who was brought to the accident and emergency department of the University of Port Harcourt Teaching Hospital, Port-Harcourt, Rivers State, Nigeria was presented.

AN UNUSUAL ECTOPIC OSSEOUS TONGUE MASS - A case report.

We report a case of tongue swelling resulting from ectopic osseous proliferation within a pseudocystic stroma in a 24 year old healthy female. The patient presented a history of dull pain and gradual onset of a swelling at the ventral aspect of the tongue. The lesion had a mixed consistency with areas of sponginess andfluctuancy interspersed with nodular bony hardness and yielded a sanguinous aspirate.

The sensitivity, specificity and accuracy of fine needle aspirational cytology in the diagnosis of oro-facial neoplasms at Lagos University Teaching Hospital, Nigeria.

Objective: The aim of the study is to compare the efficacy of fine needle aspirational cytology (FNAC) with open surgical biopsy in the diagnosis of orofacial tumours in patients seen at the Dental Centre of Lagos University Teaching Hospital from May 2005-May 2006.

Patients And Methods: Fine needle aspiration was performed on all patients scheduled for open surgical biopsy at the Oral and Maxillofacial clinic of the hospital before the open surgical biopsy was done. Forty six patients whose final histological diagnoses were oro-facial neoplasms were involved in this study.
